What is the Easiest Way to Lucid Dream?
The million dollar question.
Ultimately, the dreaming mind needs to be highly activated, AND, the dreamer needs to have a critical attitude in order to instigate a lucid dream.
There is a partially overlapping cognitive-emotional continuum that exists between waking and dreaming. Affect (emotion), tends to lean toward daytime stress = stronger dreaming; however, a resilient "can-do" attitude, a proactive approach to the day, can follow into the dreaming as a higher likelihood of successful dream outcomes.
But stress is not the only way to increase activation of the dream system. Simply by keeping a dream journal, over a short time (as brief as a few days) dream vividness and recall can get a big boost. But really, the quickest path to lucidity is to combine journaling with sleep-disruption and goal-setting (including rehearsal of stabilization techniques). Combining multiple, compatible methods has a synergistic affect. Other hacks include sleeping in a cold, pitch-black room where you won't be disturbed, when you have ample time to sleep. Sleeping in a place where you normally don't sleep also helps. And if things are taking too long, nootropic supplements can be your Matrix Red Pill. If considering the nootropic approach, keep in mind that some supplements work by inhibiting REM-sleep and causing a subsequent REM-rebound, and these should not be taken at the same time as supplements that directly empower REM-sleep or accelerate cognition. Further, some supplements which improve aspects of memory while awake completely eliminate REM recall.
